Proposed resolution (June, 2016):

Change [temp.dep.constexpr] paragraph 5 as follows:

An expression of the form &qualified-id where the qualified-id names a dependent member of the current instantiation is value-dependent. An expression of the form


is also value-dependent if evaluating cast-expression as a core constant expression (7.7 [expr.const]) succeeds and the result of the evaluation refers to a templated entity that is an object with static or thread storage duration or a member function.

According to bullet 2.4 of [temp.dep.constexpr], an id-expression is value-dependent if

  • it names a static data member that is a dependent member of the current instantiation and is not initialized in a member-declarator,

This implies that the address of an initialized static data member is not value-dependent, which is incorrect.
